Photon Counter Implemented by Field Programmable Gate Array

Abstract:

Photon correlation technique is an effective method for measuring the particle size of sub-micron particles and nanoparticles. This tenchnology has a good prospect and commerical value. Photon counter is used in photon correlation spectroscopy experiment to gain the intensity of photon. In order to obtain the accurate values of the photon correlation, efficient and accurate photon counter must be designed. This paper presents two kinds of photon counters implemented by FPGA. The programming language used is Verilog HDL. The software design and system simulation are completed in the integration circumstance of ISE. Experiments show that our work is effective. They all have a simple circuit design, and easy to be upgraded. The accurate photon counters can meet the different requirements of photon correlation.
